Blasting seismic effect on the security implications of the neighboring buildings in the dangers of blasting works has become increasingly a cause for concern, many blasting staff has done a lot of study on the characteristics of the explosion ground discovering, and also achieved fruitful results in the experimental stage, but rarely in practical applications. In this paper, we analyzed the attenuation law of blasting ground discovering for the test of engineering examples by the test results of underwater explosion container of blasting ground discovering in the laboratory conditions.In this paper, we use10g Desensitizing RDX Cartridge as the existing conditions which fitted with a single explosion in the pool project blasting vibration to simulate the explosion of single kits and kits. Measured waveform data is divided into two parts, one is the data waveform which measured in the underwater explosion the container; second is the data waveform which measured in the blasting project site. The interaction between the different extended combinations kits should be considered in order to make the test simulates situation closer to the project site.Finally, data were measured to read the blasting seismic testing systems in different cases of blasting vibration waveform.Single, double Cartridge Blasting vertical vibration speed of seismic waves and the level of vibration velocity formula were obtained by analysis the data processing. The correlation coefficient of the formula than0.97, and meet the accuracy requirements, the formula has a certain reference in the actual engineering blasting.While have a FFT conversion on the vibration waveform of measured, and we get the spectral characteristics of the phase spectrum, power spectrum, and also analyze the impact of buildings.In the data analysis of engineering blasting experimental, contrast the obtained velocity Formula and draw the velocity formula at the scene have provided a technical support for similar environmental engineering blasting.
